Most-played games range from Clair Obscur to Civ to Elden Ring to Halo 2 and beyond. There's no question Cortana is as inseparable from Halo as Master Chief himself, serving as John-117's closest companion and one of the franchise's most recognizable characters since the original Halo: Combat Evolved. Created from a flash-cloned brain of Dr. Catherine Halsey, the brilliant UNSC artificial intelligence accompanied Chief through humanity's war against the Covenant, helped uncover the secrets of the Halo rings, and repeatedly proved instrumental in saving the galaxy. Their relationship eventually became one of the emotional foundations of the series, making Cortana's apparent death in Halo 4 all the more devastating. However, her unexpected return in Halo 5: Guardians transformed the longtime hero into an antagonist, culminating in her final sacrifice and apparent redemption before the events of Halo Infinite. From there, Infinite ultimately left Master Chief ready to move forward without Cortana, while carefully setting the stage for a successor who could carry on her legacy without simply becoming another Cortana. The Weapon had a choice to make in choosing a name, and thanks to a new chapter in the Halo saga, we finally know who Cortana's official replacement is and what waits on the road ahead (via Waypoint). Edge Of Dawn Introduces Cortana's Official "Replacement" Halo: Edge of Dawn officially gives the Weapon the name Joyeuse, establishing a new identity that honors Cortana without simply recreating her. The name comes from the medieval "Song of Roland," where Joyeuse and Cortana are described as sister swords forged from the same steel. That connection mirrors the two AIs, who were both created using the cloned brains of Dr. Halsey. "Joyeuse" itself translates to "joyous" or "joyful," fitting the Weapon's curious, expressive, and more youthful personality, what creators describe as a "little sister" type. Joyeuse is certainly still connected to the legacy of Cortana, that much is as undeniable as her own serial number, but she is also a unique individual unto herself. Edge of Dawn offers a great opportunity to delve into why she chose that name and what it means to her, to really dig into Joy’s interiority and how she thinks and feels about things after the adventure she has been on through Halo Infinite’s campaign. Written by Kelly Gay, Edge of Dawn released on December 16, 2025, and picks up immediately after the events of Halo Infinite, following Master Chief, Joyeuse, and Fernando Esparza as they continue fighting the Banished on Zeta Halo. Fans can find the novel in trade paperback and ebook editions through major booksellers, while an unabridged audiobook is also available digitally, through sites such as Audible. The audio edition also features Steve Downes as Master Chief, Jen Taylor as Joyeuse, Cortana, and Halsey, Nicolas Roye as Esparza and the narrator, and Debra Wilson as the Harbinger, and it's a must-read for hardcore Halo fans and lore enthusiasts. Joy To The World: A New Beginning For Master Chief Joyeuse represents an important reset for Halo after years in which Cortana dominated the franchise's narrative identity. Rather than trying to undo Cortana's death or recreate the exact dynamic she once shared with Master Chief, Joyeuse gives the series room to explore what comes next for John-117. She has the same underlying connection to Halsey that made Cortana so significant, but her personality, perspective, and relationship with Chief are still developing. That creates an opportunity for future stories to show Master Chief building trust with someone new instead of trying to recapture the magic of iconic moments from the main series. That distinction also matters for Chief himself, as Cortana's loss has been one of the defining emotional wounds of his recent story, and Joyeuse can serve as a reminder that moving forward does not mean forgetting what came before. If anything, her presence allows Halo to preserve Cortana's legacy without being bound to or limited by it. Cortana is ultimately too important to Halo to ever be truly replaced, but Joyeuse does not need to be another Cortana, either. By carrying part of that history while establishing an identity of her own, she may be exactly the successor Master Chief and the franchise needs. If you haven't had a chance to read Edge of Dawn yet, it's well worth your time, and is a necessity if you're interested in Master Chief's growth as a character.
